Leviticus 15:22

New International Version

Anyone who touches anything she sits on will be unclean; they must wash their clothes and bathe with water, and they will be unclean till evening.

See the chapter Copy

“ ‘You will make yourselves unclean by these; whoever touches their carcasses will be unclean till evening.

Anyone who touches her bed will be unclean; they must wash their clothes and bathe with water, and they will be unclean till evening.

Whether it is the bed or anything she was sitting on, when anyone touches it, they will be unclean till evening.

Anything that an unclean person touches becomes unclean, and anyone who touches it becomes unclean till evening.”
